Answer:
Five
Step-by-step explanation:
As we know that quadrilateral contains 10 elements that involves 4 sides, 4 angles, and 2 diagonals. It cannot be drawn by four elements at least it required minimum 5 elements.
So as per the given statement, it is required to construct a unique quadrilateral for minimum 5 elements measurements
Hence, the same is to be considered
Answer:
Die is not fair given that Pvalue< 0.05, hence we reject Null hypothesis
a) H0: Die = fair
b) Ha : Die ≠ fair
c) df = 5
Step-by-step explanation:
The expected frequency of every face values = 20
a) state Null hypothesis
H0: Die = fair
b) Alternate Hypothesis
Ha : Die ≠ fair
c) degree of freedom
df = ( n - 1 )
= ( 6 - 1 ) = 5
n = sample size ( number of faces a die has )
Note : After conducting hypothesis test
Pvalue ≈ 0.0026
test statistic ≈ 18.30
Hence we can conclude that die is not fair given that Pvalue < 0.05, hence we reject Null hypothesis
